Fossils
a scientist who finds and studies fossils.
Paleontologists
comparing DNA between species to find how closely they are related
biochemical evidence
body parts of species that have similar features, indicating a common ancestor
homologous structures
the theory that states that populations of organisms change over time to become better suited to survive and reproduce in their specific environment.
evolution
Mrs. Vann was self taught with what Musical instrument?
The Guitar
fossils are used to find prof of what?
common ancestors
similarities between embryo stages in different species
embryological evidence
structures with similar function in different organisms that did not evolve from a common ancestor
analogous structures
scientist who first proposed the theory of evolution
How many pets does Mrs. Vann have?
currently 1 pet
using a fossil's position in layers of the earth to determine the age
law of superposition
humans having gills in the early stages of embryo development (is an example of what?)
embryological evidence
whales having pelvic bones in their bodies even though they don't have legs (example of what?)
vestigial structure
Those organisms that are a better biological fit for their environment will survive and reproduce better than others. Those organisms will become more numerous.
survival of the fittest
What type of Pet does Mrs. Vann currently Have
A French bulldog
using more exact measures to determine age (Carbon dating, tree rings, etc.)
absolute dating
chimpanzees and humans 99.7% of their DNA in common (this is an example of what?)
biochemical evidence
